If someone disagrees with you and the argument makes you change your opinion, you might say "Fair enough!" in English. This seems to be essentially equivalent to "Oh, good point! I agree."
Is there a similar phrase in Latin? Of course, one can use verbs like consentio or assentior, but I was hoping there would be something indicating a change of opinion — or at least something a little more colorful.
I assume something like this could be found in Plautus, but I'm not familiar with his work.
